HIGH VOLTAGE CABLE
High Voltage Cross-linked Polyethylene (XLPE) Insulated Power Cable is suitable for laying in AC 50Hz power transmission/distribution lines with a rated voltage of 3.6/6kV to 220kV. It features excellent insulation performance, high thermal stability, strong mechanical resistance, reliable operation, and adaptability to various complex laying environments (e.g., direct burial, tunnel, underwater).

High Voltage Cable SPECIFICATIONS
- The long-term permissible operation temperature of the conductor shall not be higher than 90°C.
- Conductor maximum short circuit (less than 5 seconds) temperature shall not be higher than 250°C.
- The cable is not limited by drop in level when being laid, and the minimum ambient temperature for laying shall not be lower than -20°C.
- Superior electrical insulation performance, low dielectric loss, good resistance to partial discharge, and long-term anti-aging properties.
- Strong mechanical protection: resistant to external pressure, tension, moisture penetration, and chemical corrosion (acids, alkalis, etc.), with flame-retardant options available.
- Compact structure, high current-carrying capacity, and convenient installation/ maintenance.
